survival boxes adjustments

Created by: Intigracy

survival boxes are now named survival box survival boxes spawn with single use bruisepack

changes path of box/engineer to box/survival/engineer, adjusted everywhere it's used accordingly checked our 4 main maps (box, meta, deff, taxi), none of them use box/engineer so I don't have to edit the maps

removed partial pathing all over boxes.dm

fixes #4932 (closed)
